The engine speed of your Vauxhall works thanks to the throttle body. If the model of your Vauxhall does not have a petrol engine, don't bother searching, you will not find a throttle body.
The throttle body of your Vauxhall can be divided into three parts:
- the body.
- the throttle or butterfly valve,
- the automatically controlled pressure regulator.
In general, the Vauxhall throttle body can be found level with the intake manifold.
